Dark cloud in Scorpius
No light shines from the dark regions shown in the picture on the left. This might lead you to think nothing actually exists there. Yet in those seemingly dark regions between the stars exist giant gas and dust clouds full of molecules that emit radiation in the form of radio waves. Such radiation, while invisible to our eyes, is easily detected by the BIMA array. By using the BIMA array, astronomers can not only detect molecules but also "see" into the giant clouds that contain them.

Optical, infrared, X ray and other radiotelescopes
provide alternative windows onto the universe, each revealing distinct information.
By combining observations from the BIMA array with those from other types of telescopes, astronomers gain a more complete information about chemistry in space, star formation, and galactic evolution.
